[0002] The wheat water-fertilizer integrated drip irrigation control system is an efficient agricultural irrigation management method that aims to optimize the supply of water and fertilizer simultaneously through drip irrigation technology to increase wheat yield and quality. Through precise water and fertilizer management, it can effectively improve the utilization efficiency of water resources and fertilizers, improve crop growth and yield, while reducing costs and environmental impacts, and promoting sustainable agricultural development.

[0003] Through drip irrigation technology, water and fertilizer can be delivered directly to the roots of plants, reducing evaporation and leakage. It can accurately apply required nutrients according to the growth needs of wheat and reduce fertilizer waste.

At the same time, improper frequency of drip irrigation and fertilization may also lead to nutrient imbalance and affect crop growth. Appropriate analysis and adjustment can help the control system overcome difficulties and improve the system's operating efficiency and crop yields. Summary of the invention

Represents the sum of all data points in the collection interval. The soil nutrient concentration change value TYFbz is calculated by dividing the sum of the absolute differences between all data points in the collection interval and the previous data by the sum of all data points in the collection interval; The algorithm formula of the crop growth change value NSZbz is as follows: In the formula, i=2 in the table means that the calculation starts from the second data in the growth data set, that is, NSZsj2, and ends with the last data in the data set, that is, NSZsj. N End, |NSZsj i -NSZ i-1 |Representing NSZsj i The absolute difference between the previous data, Represents the sum of the absolute differences between all data points in the collection interval and the previous data. Represents the sum of all data points in the collection interval. The sum of the absolute differences between all data points in the collection interval and the previous data is divided by the sum of all data points in the collection interval to calculate the crop growth change value NSZbz.

6. The wheat water-fertilizer integrated drip irrigation control system according to claim 5, characterized in that: The soil moisture difference Tsdcz algorithm formula is as follows: Tsdcz=TRSJ dq -TSDbz In the formula, TRSJ dq Represents the current soil moisture data. The soil moisture difference Tsdcz is calculated by subtracting the soil moisture change value from the current soil moisture data; The soil nutrient difference Tyfcz algorithm formula is as follows: Typh=TRYFSJ dq -TYFbz In the formula, TRYFSJ dq Represents the current soil nutrient concentration data. The soil nutrient difference Tyfcz is calculated by subtracting the soil nutrient concentration change value from the current soil nutrient concentration data; The growth height difference SZcz algorithm formula is as follows: SZCZ=NSZSJ dq -NSZbd In the formula, NSZSJ dq Represents the current crop growth data, based on the current crop growth data NSZSJ dp Subtract the crop growth change value and calculate the growth height difference SZcz.

7. The wheat water-fertilizer integrated drip irrigation control system according to claim 6, characterized in that: The control and adjustment module adjusts the growth regulator according to the growth height difference SZcz. If the growth height difference SZcz is a negative number, it means that the current height of the wheat is too low, and a signal is sent to the adjustment control module for growth promotion adjustment. If the growth height difference SZcz is a positive number, it means that the height of the wheat is too high, and a signal is sent to the adjustment control module for growth inhibition adjustment.

8. The wheat water-fertilizer integrated drip irrigation control system according to claim 7, characterized in that: The control and adjustment module automatically adjusts the time according to the water volatilization rate SHFsd. If the water volatilization rate SHFsd changes, the data analysis module sends a signal to the adjustment control module, and the drip irrigation time automatic adjustment unit receives the signal and automatically adjusts the time. The timing device performs timed drip irrigation according to the water volatilization rate SHFsd.

9. The wheat water-fertilizer integrated drip irrigation control system according to claim 8, characterized in that: When the soil moisture difference Tsdcz is a positive number, it means that the current soil has too much moisture, and a signal is sent to the control and regulation module to automatically reduce the drip irrigation frequency. When the soil moisture difference Tsdcz is a negative number, it means that the current soil is short of water, and a signal is sent to the control and regulation module to automatically increase the drip irrigation frequency.

10. The wheat water-fertilizer integrated drip irrigation control system according to claim 9, characterized in that: When the soil nutrient difference Tyfcz is a positive number, it means that the current soil fertilizer content is high, and a signal is sent to the control and regulation module to automatically reduce the amount of fertilizer injected. When the soil nutrient difference Tyfcz is a negative number, it means that the current soil fertilizer content is low, and a signal is sent to the control and regulation module to automatically increase the amount of fertilizer injected.
